Peak Hold Function - Kometec MD 9273 Bedienungsanleitung

MD 9273 Leakage Clamp Description of Test Functions
In this mode, data retention and registering of maximum and minimum values is possible by using the H key.

Peak hold function

In this function, the peak value of the waveform is shown. The peak value is the highest measured value
within one period of the waveform and is usually higher than the effective value (also known as the TRMS
value), e.g. for a perfect sinusoidal signal the peak value is 1.41 times the effective value. Peak hold is
executed with a faster sampling than other measurements at 25 µs.
Inrush Current measurement (Current functions only)
Inrush current is the maximum instantaneous current drawn by a circuit when first turned on, expressed as
TRMS value. It is meant for use with motors and other loads that draw high initial current.
Additionally it is possible to connect the voltage probes and the instrument calculates the minimum RMS
voltage of the initial signal.
